I dunno about everyone else, but I consider chainrings along with rear sprockets (not to mention chains) to be consumable items to some extent. So I'm less concerned about what I can snag as a bundle with a new crankset, than what is available in terms of new or used chainrings in the relevant BCD sizes.
Therefore, I recommend you research what replacement chainrings are available for your inner/middle/outer chainring preferences, and then select a crankset that supports the available BCD sizes.
Hints:
  • 110 and 130 BCD outer/middle are very common (i.e. lots of available chainring tooth counts)
  • 74 BCD inner is very common (i.e. lots of available chainring tooth counts)
  • 144 BCD outer/middle used to be common, and with a 74 BCD inner it can also be a good option
  • other sizes are rather specialized and you will be going down a rabbit hole if you choose a crankset with other than the above mentioned BCD sizes
